A teenager who raped a woman in her New York City apartment while she slept next to her seven-year-old daughter was sentenced to 13 years in prison on Monday.

Cesar Lucas, 18, was unapologetic toward his victim, Kia Graves, a 37-year-old former actress, The New York Post reported. Graves said she will try to forgive Lucas, but she couldn't forget what he had done.

Lucas admitted raping Graves in her Upper West Side apartment when he was 16 in September, 2012 because he was "feeling horny." He was out making a pizza delivery for his father's restaurant, Sal's Pizza.

In a handwritten and poorly worded confession, Lucas both admits that he raped Graves, but also tries to blame his victim, according to The Daily Mail.

In the confession, bizarrely written in the third person, he said he had "this type of feelings he had never felted before which led him to do things he would never think he would do in his life."

The confession continues:

"I unrap her from all the coushing she had on top of her ... She also started to feel horny, you can say ... She was completely drunk. I really was pretty scare because she was drunk and I kind ah took advantage of her."

He blamed his actions on a "disease."

"Cesar got type of disease in a way he never had felted before," he wrote.

The note went on to say that he raped Graves for two minutes while her daughter slept in the same bed. He then stole her daughter's iPhone and $20 from the girl's wallet before leaving.

When police arrested Lucas later, he tried to claim he had already been arrested for the same thing, citing a previous arrest for breaking into another apartment.

"What's going on? Why are you arresting me? I've been arrested before for the same thing. I broke into an apartment. It's still pending. I have to go to court," he told arresting officers.

Graves said she had left her door unlocked because her mother lives across the hall, according to CBS New York.

She still lives in the same apartment, but said her life is in shambles after Lucas attacked her.

"I have nightmares thinking that he's getting out of jail, and I wake up all the time making sure my door is locked," she said. "I sleep with one eye open, basically. I have panic attacks and I wake up in sweats."

Graves said she's seeing a doctor and hoping to improve.

"There's constant fear and anxiety," she said.

Lucas' lawyer, Gary Villanueva, said his client was sorry for what he'd done, even though Lucas made no comment.

"He's a remorseful young man from a caring, decent and solid family," Villanueva said.

Lucas pleaded guilty rape and other charges. He was also sentenced to 20 years of post-release supervision. Graves said he "deserves everything the court is sentencing him to today."

Graves is also suing Sal's Pizza and the former night doorman at the apartment building, who was fired after the break-in.
